基于matlab的纯电动汽车建模及动力特性仿真分析

摘要

This paper establishes a electric vehicle system and whole vehicle model in which lithium-ion batteries are used as power source and variable frequency AC induction motor as power conversion device, and simulates and analyzes the vehicle dynamic, characteristics,such as the vehicle speed,acceleration,climbing ability and energy consumption.The results prove that the model is reasonable and feasible.%建立了以锂电池组为动力源,交流异步变频电动机为动力转换装置的纯电动汽车的动力系统及整车模型,在mat1ab/simulink平台上对该模型的车辆速度、加速度、爬坡能力、能耗等动力特性进行了仿真分析,结果表明该模型方案设计合理可行.
